PPT-Chapter 27 Interference and the Wave Nature of Light

Dr Quantum 271 The Principle of Linear Superposition When two or more light waves pass through a given point their electric fields combine according to the principle of superposition The waves emitted by the sources start out in phase and arrive at . And 57375en 57375ere Were None meets the standard for Range of Reading and Level of Text Complexity for grade 8 Its structure pacing and universal appeal make it an appropriate reading choice for reluctant readers 57375e book also o57373ers students Wave Behavior. When waves encounter new mediums, barriers, or other waves they can behave in different ways. In physics these behaviors are described using some of the . following terms. .. Reflection. Introduction to Physics II. . Class 5 – . Outline:. Ch. . 22, . sections . 22.1-22.4. (Note we are skipping sections 22.5 and 22.6 in this course). Light and Optics. Double-Slit Interference. The Diffraction Grating. Wave Optics. The wave nature of light is needed to explain various phenomena. Interference. Diffraction. The . particle nature of light was the basis for ray (geometric) . optics. Light waves interfere with each other much like mechanical waves do. Dr. Mahender Singh. Associate Professor in Physics. Post Graduate Govt. College Sector-11. Chandigarh. Interference. The term interference refers to phenomenon involving superposition of waves leading to a modification of their intensity in the region of superposition.. Physics 2102. Gabriela Gonz. á. lez. Light is a wave. When two beams of light combine, we can have constructive or destructive “interference.” . http://www.colorado.edu/physics/2000/applets/fourier.html. INTERFERENCE:. When two wave trains of the same frequency & the same amplitude traveling in the same direction are superimposed on one another they produce interference. If at any point the waves are in phase, there is an increase in resultant amplitude, i.e. . T. ypes of wave interactions. Reflection. Refraction. Diffraction. Interference. Reflection. The bouncing back of a wave when it hits a surface.. * NOTE: When waves hits a substance some of it is transmitted and some of it is reflected.. REFLECTION. Reflection. is where a wave strikes an object and bounces off.. When a wave strikes a flat reflective surface it will reflect back at the same angle at which it struck the surface. This is called the Law of Reflection.. Chapter 9: Electrons in Atoms and the Periodic Table. Learning Goals. Compare the wave and particle natures of light.. Define a quantum of energy, and explain how it is related to an energy change of matter.. Electromagnetic Spectrum and Spectroscopy. 0. Innovators Presentations. Pictures from Week 3 Conservatory Field . Trip. Questions from reading assignments?. Light moves at light speed. Wave Properties of Light. Bellringer – 2 . mins. to hand in. Describe why you think rainbows sometimes pop up after it rains.. DO WORK. STOP. Objectives. Be able to fully explain exactly how rainbows, sunsets, sunrises, polarization, and diffraction work.. PROPERTIES OF LIGHT. Light are energy. It travel in the speed of . m/sec . It has dual nature of both wave and particles.. . As wave-. . It propagate itself through a disturbance of electric and magnetic field being perpendicular to each other.. this week and have started doing the first Mastering Physics assignment. . due on Friday. . !! .
